Answer: 35.

Step-by-step explanation:

The absolute value of a number is the non-negative value of the number without regard to its sign. It may be thought of as the distance of the number from zero on a number line. It is symbolized by two vertical lines, as |3| or |−3| is equal to 3. For complex numbers, the absolute value is the positive square root of the sum of the squares of the real and imaginary parts. The absolute value is used to determine the numeric value of a quantity, irrespective of sign, that has no meaning for the sign.

To find the absolute value of -16+51, you need to simplify the expression first and then apply the definition of absolute value. -16+51 = 35, so | -16+51 | = | 35 |. Since 35 is a positive number, its absolute value is itself. Therefore, | -16+51 | = 35.

Answer:194.99 with tax and you save 105 dollars. without tax, your price total is 206.69 and you save 111.30.

If x is the total earnings in a year then 0.20x = 1400000 will be the equation and the second picture best represent the problem.

The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.

The percentage is also called the indicating hundredths.

Let's x is the total earnings in the year.

As per the given question,

20% of total earnings x is $1400000

Then, 20 % of x = 1400000

(20/100)x = 1400000

0.20x = 1400000

The 20% of 100% is the little (1/5)th portion of the circle which is shown in the second picture correctly.

Hence"If x is the total earnings in a year then 0.20x = 1400000 will be the equation and the second picture best represent the problem".

Answer:

{a , c}

Step-by-step explanation:

first find u intersection p

n(U n P ) = {a , b , c , d} n {b , d , e}

={d , b}

intersection means element or values which lies in both the sets

now to find p complement

note : p( bar at the top ) is read as p complement

p complement = n(U) - n(U n P)

={a , b , c , d} - {d , b}

={a , c}

n(U) -n(U n P) means the elements which is only in n(U ) but not in n(U n P)

Answer:

3.14159

Step-by-step explanation:

Answer:

\(( {x}^{2} + 16x + 64) - (x + 8)(x - 4) = k(x + 8) \\ ( {x + 8)}^{2} - (x + 8)(x - 4) = k(x + 8) \\ (x + 8) - (x - 4) = k \\ k = (x - x) + (8 + 4) \\ k = 12\)

Answer:

Step-by-step explanation:

a² + 2ab + b² = (a + b)²

2ab = 2 * x * 8 = 16x

x²  + 16x + 64 = x² + 2* x * 8 + 8²  

                      = (x + 8)²

x² + 16x + 8 - (x +8)(x - 4) = (x+8)² - (x+ 8) (x -4)

                                        = (x +8)(x +8) - (x + 8)(x - 4)

(x +8 ) is common in both terms

                                        = (x + 8) [ (x + 8) - (x - 4) ]

                                        = (x + 8) [ x + 8 - x + 4 ]  

{Combine like terms. so x + (-x ) = 0   and 8 +4 = 12}

                                         = (x + 8) [ 12]

k = 12

Answer:

Perimeter is 12mm, height is \(2\sqrt3\)mm in simplest radical form, and 3.5mm in approximate decimal form.

Step-by-step explanation:

The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.

For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem (\(a^2+b^2=c^2\)) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.

I've enclosed an attachment for that.

Answer:

5 quarters, 1 nickel  

Step-by-step explanation:

A combination of coins which is equivalent to 130% of a dollar is equal to 8 quarters,2 dimes and 2 nickels.

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”

Given: A dollar and to find its 130% equivalent in the form of coins.

A nickel is worth 5 cents

A dime is worth 10 cents

A quarter is worth 25 cents

Now a dollar is equivalent to 100 cents

Thus 130% of a dollar is equivalent to

130/100 ×100 +100 =230 cents

Therefore a combination of 8 quarters which is equal to 200 cents and 2 dimes and 2 nickel is equal to 230 cents  as

8×25+2×10+2×5=230 cents.

Hence, A combination of coins which is equivalent to 130% of a dollar is equal to 8 quarters,2 dimes and 2 nickels.
